Baffle A device used to direct sound in a particular direction. Billet Cylinder Head Any component that has been machined from a solid billet. The billet will have been rolled or forged, not cast. The billet is then machined into a component. Breakout Used only in handicap racing, "Breakout" refers to a competitor running quicker than their "dial-in" (i.e. ran a time quicker/ lower than their prediction). Unless the opponent commits a more serious foul (e.g., red-lights, crosses the centreline, or fails a post-race inspection), the driver who breaks out loses. If both competitors breakout, the one who runs closest to his or her dial is the winner. Burnout Spinning the rear tyres in water to heat and clean them prior to a run for better traction. A burnout precedes every run. Butt Weld The “butting” together of two pieces of material for welding, without external reinforcement, overlap or “sleeving”.
